The active device array substrate includes first substrate and active device array layer. The color filter substrate includes second substrate, black matrix layer, overcoat layer, and color filter layer. The color filter layer includes color filter patterns in the active region and dummy color filter patterns in the peripheral region. The color filter patterns and the dummy color filter patterns define blank areas outside areas of the color filter patterns and the dummy color filter patterns arranged in a first direction. The blank areas include first blank areas in the active region and second blank areas in the peripheral region and the first blank area has a width different from at least one of the second blank areas in the first direction.
